Note that by installing any Vivaldi version (tech preview, snapshot, etc.), the package automatically adds the Vivaldi stable repository (at least in Ubuntu/Debian) and if you install multiple Vivaldi versions, it may result in duplicate repositories - this can be fixed by deleting the extra vivaldi-*.list repository file from /etc/apt/sources.list.d/.
